  • Magnetic seal assembly
    Patent number: 11333253
    Abstract: A magnetic seal assembly comprises a metallic annular wear seal. A magnetic seal has a magnetic annular body adjacent to and attracting the wear seal into contact against a contact face thereof. A retainer ring is connected to a surface to the magnetic seal, the retainer ring having a coefficient of thermal expansion different than a coefficient of thermal expansion of the annular body, the coefficient of thermal expansion of the retainer ring selected to constrain a thermal expansion of the annular body. A method for controlling a thermal expansion of a magnetic seal assembly is also provided.
    Type: Grant

  • Bearing assembly with inner rings and method of alignment
    Patent number: 10876578
    Abstract: A bearing alignment assembly comprises an outer ring. An inner ring assembly is disposed radially inwardly of the outer ring and cooperating therewith to form a roller volume. The inner ring assembly has a forward inner ring and an adjacent aft inner ring cooperating to provide an inner surface of the inner ring assembly. The forward inner ring includes axial grooves extending axially along and circumferentially spaced around a forward portion of the inner circumferential surface of the inner ring assembly.
